VLF Hipot Tester With Tg Tan Delta Measuring

I, Overview

Our new generation ： AC 0.1hZ VLF hipot tester with tg tan delta measuring is the core product independently developed by using the latest American technology, using 7-inch touch mode screen, the latest ARM7 single-chip computer, high-speed AD acquisition circuit, and equipped with background management software.It is suitable for the huge capacitance electric products (such as power cables, power capacitors, large and medium-sized generators and motors, etc.) to do withstａnd voltage test and measuring the tg tan delta value.

II. Feature

1. Advanced technology: using digital frequency conversion technology, microcomputer control, boost, decrease-voltage, measurement, protection and other testing process is fully automated.

2.Equipment operation: simple wiring, easy to use.

3.Comprehensive protection: multiple protection (over-voltage protection, high and low voltage side over-current protection), rapid action (active time: 10ms), the instrument is safe and reliable.

4.Safe and reliable: the controller and high voltage generator low voltage side are in connection, photoelectric control, safe and reliable use

5. The high and low voltage closed-loop negative feedback control circuit is adopted to output no allowable capacitive rise effect.

6.Complete configuration: capacitive touch screen, LCD English character display, automatic storage, automatic printing.

7.Large test range: 0.1Hz, 0.05Hz,, 0.02Hz multi-frequency selection, large test range.
